Re: johnson faststrike 150 problems
Up until recently I owned a 1996 115HP (V4)Faststrike. I say up until recently because now the motor is sitting at the wreckers due to a problem inherent with this particular model of motor. The first sign of the problem was exactly as you have described with your motor (ie running like a charm most of the time, dropping revs etc).<br /><br />The problem surrounds the exhaust "u-tube" or I think the proper name is "exhaust tube inner". Instead of seand a burst of pure exhaust back into the engine as per design, a small amount of water settles at the lowest point of the tube and when the hot exhaust hits it, the result is a burst of exhaust / steam shooting into the powerhead. This causes condensation (water) to build up in my case in #4 cylinder. My motor had less than 170 hours on it and the repair bill was in excess of $7,000 (AUS), hence the retirement to the wreckers.<br /><br />OMC or Bombardier whatever they call themselves were only too happy to offer absouletly no help at all. This may not apply to your motor, but it would be worth a look.
